If I recall correctly, I think the shutzen squad was mean to only be included in selectors from the Western Desert book. The free LMG was meant to offset the cost of every selector that they were allowed in being motorized which means you have to buy a truck for them. So when you buy that squad now you have to pay 39 points for a truck to transport them as well, so a free LMG for the unit helps balance back the cost to use these units.
Now, if the shutzen squad is allowed to be in the generic platoon selector is kinda ridiculous and throws off the balance then.
